Deburr, Blend and Finish Stainless Steel

3M Cloth Belt 777F is specially designed to deburr, blend, and finish stainless steel and other heat-sensitive alloys. It contains a grinding aid that reduces running temperatures, making it ideal for use on stainless steel, nickel alloys, and cobalt alloys. The abrasive grain is bonded to the backing with resin, ensuring durability even under high heat and pressure. This belt is recommended for dimensioning parts, deburring, blending, and finishing castings and forgings.

Ceramic Abrasive Grain Boosts Performance

For enhanced performance, 777F products feature a blend of aluminum oxide and 3M ceramic abrasive grain. This combination results in a harder and longer-lasting abrasive compared to traditional aluminum oxide abrasives. The ceramic/aluminum oxide blend excels in cut-rate and durability, making the Cloth Belt 777F an excellent choice for moderate stock removal and surface preparation.

Sized to Suit Your Needs

These abrasive belts are available in various widths and lengths, catering to both wood and metal sanding applications. 3M offers a wide selection of belts that can fit most industrial belt sanders. Wider belts are used with wide belt sanders for dimensioning or finishing wood panels, smoothing rough-cut edges of metal sheets, or adding a grain pattern to stainless steel sheets. Medium-width belts are suitable for edge sanders, allowing for sanding flat and narrow surfaces such as panel edges. Narrow belts are used with portable belt sanders for sanding or blending wood pieces like cabinet doors.

Find Your Flex

Belts come with different flexibilities and splices to join the belt ends. 3M Cloth Belt 777F features a film splice, providing added strength for grinding in high-pressure applications. For increased flexibility and conformity, an L-flex is available, offering a softer touch for finishing and blending. If maximum flexibility is required, a full flex belt is the most flexible option.
